Tracking Bandwidth on Red Hat?

By Paul Sands - Jul. 01, 2008

How can i track all the incoming and outgoing traffic on Red Hat mail server, where i am using sendmail as a mail server? Usually my incoming bandwidth is around 800 kbps but for the last few days it had increased to 2500 kbps even though i haven't added any users recently. Any ideas on why this might be happening and what can I use to monitor this?
